IMPROVEMENT IN ROOFING COMPOUNDS.

Specification forming part of Letters Patent No. 116,983, dated July 11, 1871.

To all whom it may concern:

Be it known that I, HARRIIE MQRRIE, of Rockford, in the county of Winnebago and State of for Roofing Purposes; and I do hereby declare that the following is a full, clear, and exactdescription thereof, enabling those skilled in the art to make and use the some.

To prepare the compound, take the following ingredients in about the proportions named: yooal-tar of co1umew igboilfidilul; about. tggntv-six gallons. W'ith tins residuum, liileliot, mixjiity )ounds of )ii'('ll. agitating thc'niixture until the pitc is dissolved and has thoroughly combined with the tar. Let the mixture partially cool, and then add twen nnds of water-lime cement. twentv pounds of nmrhle-dusnlyy mm '1 ust-er'ot' Paris. on us i sou stone. twentv-u've pounds of around slate. two pollll s 0i native rubber cut in eng ne am pounds of pulverize rod load uulxedgyitlul ree Zillonsoi rzi'iv hnsl-ed-o In the mean time disrive five ponno mf )0T-2lbh. 1- 1LP OI1 I I 1S Q gum shellac. I8 l l RQ ll ll(lS 0; nine. gndjw entygnm ot asnnnltum p a sufiicientquantity of boilinsr water. and a d this mixture with that heretofore described. In making a new roof in sufficient quantity of the above composition is taken and enough sand Examiner i added to give to it the consistency of coininon J mortar. This is spread on the boards of the roof to the thickness of about one-fourth of an inch, and left to dry. As soon as it-beoomes thus dried and hard it is coated, by means of a brush, with the composition, sufiiciently heated to a semi-fluid state for that purpose, without the admixture ofsand.

For recoating and repairing, old roofs myoomposition is applied in a semi-fluid state witha large brush. The rays of the sun readily dry and harden it, and, though elastic, it is not liable to run, so that the use of sand or gravel may be dispensed with, and the weight of a roof which is very considerable and objectionable when sand or gravel is thus employed, materially reduced.

What- I claim as my invention, and desireto secure by Letters Patent, is--' The manufactiire or prepa-ration'of a coinpound for roofing purposes of the ingredientsand in substantially the proportions set forth.

In testimony whereof I have signed my nameto this specification in thepresence of two subscribing witnesses.

BARBIE MORRIE.
